UNTTED STATES PATENT OFFICE.

JOSEPH B. NEFF, OF BURLINGTON, IOWA, ASSIGNOR TO THE HAPGOOD PLOW COMPANY, OF ALTON, ILLINOIS.

PLOW.

SPECIFICATION forming part of Letters Patent No.' 380,658, dated April 3, 1888.

Application tiled January 13, 188B. Serial No. 260,624.

To @ZZ whom it may concern.-

Be it known that I, JOSEPH B. NEFF, a citi- Zen of the United States, residing at Burlington, in the State of Iowa, have invented a new and useful Improvement in Plows, of which the following is a specification.

My invention relates to plows having a beam, with handles connected to the beam, and has the object to improve the method of adjusting the beam, so that the beam maybe more readily moved and adjusted and be made either for three-horse or for two-horse working, as may be desired.

Referring to the drawings, like letters referring to like paris in all the figures, Figure lis a top view of anfordinary plow with my improvement connected therewith in the block a, interposed between the handle and beam. Fig. 2 is a land-side elevation view of same, showing how the said block may be moved to the outside of the handle. Fig. 3 is a rear end View of the plow shown in Fig. 1. Fig. 4 is a detail view, enlarged, of the parts, same as is shown in Fig. 1. Fig. 5 is a perspective view, enlarged, of the block a,- and Fig. 6 is a detail view showing the block attached to the inside of the beam, where it maybe carried when not in use otherwise.

My improvement may be used in plows of any ordinary construction having the plow B, with the standard O, the beam A, and the handles H, all of ordinary construction, except as modified to embrace my invention, as shown in the drawings. The said beam has a recess or gain, b, as ordinary, cut in one side of its rear end, and the handle has Abeen directly seated in said gain and secured thereto by a l bolt through both handle and beam.

a represents my improved adj usting-block, preferably constructed of iron, about one inch thick, and it may be chambered out to lighten its weight, and of an outline diamond-shaped of about the same shape as the seat of the said gain, and with a slotted perforation, c, as will be understood by the drawings. The said perforation c is preferably made long slotted to adapt the block for its interchangeable use, as hereinafter shown.

In constructing my improved plow I usually put the parts together as shown in Fig. 2, in

(No model.)

which the handle is seated directly in the said gain and the said block placed outside of the handle, with the bolt e seated through the three parts, holding them securely' together, and when the block is so used outside of the handle it materially strengthens the handle at what was before the weakest place in the han- 'dle, in which condition the front end of the beam is set from land for a two-horse plow, as shown by dotted linesin Fig. 1. Then, when desired to adjust same and make it set for three-horse plow, the bolts securing the standard are first loosened, then the bolt e removed, the block moved and interposed between the handle and beam, and the same bolt, e, returned through the threeuhandle, block, and beam; then the standard-bolts again tightened and the beam made secure in its new position, with its front end over land for a three-horse plow, as shown in Fig. 1, avoiding all springing and warping of the handle.

It will be observed that the handles are attached to the plow and connected by the brace rungs or rods m, as usual, and that the one handle is a brace and support to the other through said rods, and forming a rigid support for the rear end of the beam. It will also be observed that when the beam is loosened in its standard-connection and the handle-securing bolt removed the beam is free to swing and 'be moved without warping, springing, or twisting the said handles, or any other part of the plow, and also that the said block may be used either between the handle and beam or outside of the' handle, with the same bolt connecting them. It is obvious that the said block may be placed on the inside of the beam to be carried, as shown in Fig. 6, in which case the same securing-bolt may be used, as before.

I am aware that blocks and wedges have heretofore been used to point the beam to or from land. Such I do not broadly claim; but I am not aware of any heretofore use of an interchangeable block interposed between the beam and handle, seated in a recess formed in the beam, with a bolt passing through the three parts-handle, block, and beam---asI herein shown and claimed.

Having thus set forth myinvention,I claim- The interchangeable block provided with IOO the slotted perforation, adapted to be used on and a bolt seated through the said three the outside of the handle as a strengtheniugparts-handle, block, andbeam-substantially Io support to the handle, or interposed between as and for the purpose set forth.

the handle and beam in converting the plow 5 into a three-horse plow, or placed on the in- JOSEPH B NEFF' side of the beam to be carried, in combination Witnesses: with abeam provided with a recess on the side E. S. LINBORGER,

of its rear end, a handlel seated in said recess, CHARLES HARRIS.
